Similar to the earlier Lindenis V5 designed for AI video processing and 4K encoding, Lindenis has released another single-board computer that uses SoM and baseboard design for 4K camera applications called the Lindenis V536.
The Lindenis V536 which runs on a new Allwinner dual Cortex-A7 processor and a single MIPI SCI interface was designed for applications that rely heavily on popular open-source packages such as Live555, V4L2, FFmpeg and custom framework, and libraries. Capable of doing a lot on image signal processing and video encoding/decoding functions, the Lindenis V536 is suitable for sample applications like 4K camera applications, media player applications, and low-latency A/V streaming applications. It supports functions like image mirroring and flipping, color enhancement and adjustment, bad pixel, and lens shading correction, providing ISP tools for the PC, contrast and sharpness enhancement, motion smear and color noise removal, real-time multi-stream encoding capability, eight ROI encoding as well as MJPEG / JPEG baseline encoding.
Hardware features and specifications include:
- Dimension: 130 x 85mm
